Gears? It is a browser extension like Flash or QuickTime/Media Player. However Gears works with the browser to enhance web based applications. It can create local database and file storage, and run JavaScript in the background to update them without slowing down the browser.

Gears has been in the making for over a year and is well known among the web developers. Currently it supports Firefox versions 2 & 3 and Internet Explorer versions 6 & 7. Safari 3 support is coming soon.

On WordPress.com it is used to store all images and other web page components from the admin area to the user’s PC, speeding up access and reducing unnecessary web traffic.

The speed increase is most noticeable when Internet is slow or on high latency and makes everybody’s blogging experience more enjoyable.

How do you turn it on for your blog ?

To enable this new feature, click on the “Turbo” link and follow it to Gears’ site to install it in your browser (if not already installed). Then the browser will have to be restarted and after logging back in WordPress, click the “Turbo” link again to give permission to Gears to work on WordPress.com.

After that Gears will download around 200 files and store them on your PC. It will also update them when needed automatically in the background, no other actions are required.
